Etymology Referring to the type locality, San Antonio, an "arhuaque" (Arawak) village.

Diagnosis A medium-sized, yellow species with conulate humerus in both major and minor, when seen in dorsal-oblique view. Close to caulicolaHNS of Costa Rica but with less prominent humeri, longer antennal scapes, and broader, more angulate postpetiolar node in both castes, as well as completely foveolate central pronotal dorsum in the major. Also similar but less so to chalcaHNS, chalcoidesHNS, mincanaHNS, schmalziHNS, and tragicaHNS.

Range Known only from the types of arhuacaHNS sensu str. (Colombia) and of its variety bimonsHNS (Ceara, Brazil).

Biology Forel found the type colony under a dried pat of cow dung.
